CEG vs VST

WACC Comparison: Constellation Energy (CEG) vs Vistra Energy (VST)

To compare the Weighted Average Cost of Capital (WACC) of Constellation Energy (CEG) and Vistra Energy (VST), we need to consider each company’s capital structure, cost of debt, cost of equity, and tax rate. WACC represents the average cost of capital for a company and is commonly used as the discount rate in Discounted Cash Flow (DCF) analysis. The following analysis compares the WACC of the two companies, with calculations based on estimated data due to limited access to the latest financials.

1. WACC Calculation Formula

WACC is calculated using the following formula:

\[ \text{WACC} = \left( \frac{E}{V} \cdot R_e \right) + \left( \frac{D}{V} \cdot R_d \cdot (1 - T_c) \right) \]

• \( E \): Market value of Equity
• \( D \): Market value of Debt
• \( V \): Total capital value (\( E + D \))
• \( R_e \): Cost of Equity
• \( R_d \): Cost of Debt
• \( T_c \): Corporate Tax Rate

2. Company Overview

• Constellation Energy (CEG): The largest carbon-free energy producer in the U.S., primarily supplying power through nuclear and renewable energy. It gained attention recently for its agreement with Microsoft to restart the Three Mile Island nuclear plant, with its stock price rising 119% in 2024.
• Vistra Energy (VST): Produces power from diverse sources, including natural gas, coal, nuclear, and solar, serving commercial and residential customers. Its stock price surged 182% in 2024, outpacing CEG.

3. Key Assumptions for WACC Analysis

Due to limited access to the latest data, this analysis uses general industry data and assumptions. Accurate WACC calculations require the latest financial statements (debt, equity ratios, market values) and Capital Asset Pricing Model (CAPM) for cost of equity estimation.

Assumptions

1. Corporate Tax Rate (\( T_c \)): Assumed at 25%, considering the U.S. federal corporate tax rate of 21% plus state-level variations.
2. Risk-Free Rate: Based on the 10-year U.S. Treasury yield, assumed at 4.5%.
3. Market Return: Long-term S&P 500 average return, assumed at 10%.
4. Beta:
   • CEG: Stable nuclear-focused business, beta estimated at 0.8–1.0 (energy utility sector average).
   • VST: Higher risk due to coal and natural gas reliance, beta estimated at 1.0–1.2.
5. Cost of Debt (\( R_d \)): Utility companies typically have a cost of debt between 4–6%. CEG assumed at 4.5% due to stable operations; VST at 5.5% due to higher risk.
6. Capital Structure (E/V, D/V): CEG assumed at 60% equity/40% debt; VST at 55% equity/45% debt, reflecting VST’s slightly higher debt reliance due to coal and gas operations.

Cost of Equity (\( R_e \)) Calculation

Using the CAPM formula:

\[ R_e = R_f + \beta \cdot (R_m - R_f) \]

• \( R_f \): Risk-Free Rate (4.5%)
• \( R_m - R_f \): Market Risk Premium (10% - 4.5% = 5.5%)

CEG:

• Beta = 0.9
• \( R_e = 4.5\% + 0.9 \cdot 5.5\% = 4.5\% + 4.95\% = 9.45\% \)

VST:

• Beta = 1.1
• \( R_e = 4.5\% + 1.1 \cdot 5.5\% = 4.5\% + 6.05\% = 10.55\% \)

WACC Calculation

CEG:

• Equity ratio (\( E/V \)) = 60%, Debt ratio (\( D/V \)) = 40%
• Cost of Debt (\( R_d \)) = 4.5%, Tax Rate (\( T_c \)) = 25%
• \( \text{WACC} = (0.6 \cdot 9.45\%) + (0.4 \cdot 4.5\% \cdot (1 - 0.25)) \)
• \( \text{WACC} = 5.67\% + (0.4 \cdot 3.375\%) = 5.67\% + 1.35\% = 7.02\% \)

VST:

• Equity ratio (\( E/V \)) = 55%, Debt ratio (\( D/V \)) = 45%
• Cost of Debt (\( R_d \)) = 5.5%, Tax Rate (\( T_c \)) = 25%
• \( \text{WACC} = (0.55 \cdot 10.55\%) + (0.45 \cdot 5.5\% \cdot (1 - 0.25)) \)
• \( \text{WACC} = 5.80\% + (0.45 \cdot 4.125\%) = 5.80\% + 1.86\% = 7.66\% \)

4. Comparative Analysis

• WACC Results:
  • CEG: Approximately 7.02%
  • VST: Approximately 7.66%
• Interpretation:
  • CEG’s Lower WACC: Due to its stable nuclear-focused business and lower beta, CEG has lower costs of equity and debt, indicating lower risk for investors and cheaper capital acquisition.
  • VST’s Higher WACC: Higher operational risks from coal and natural gas, along with a higher beta, result in elevated costs of capital and debt, reflecting greater investment risk.
• Investment Attractiveness:
  • A lower WACC means CEG can achieve profitability on projects with lower returns, making initiatives like the Three Mile Island restart more likely to be profitable.
  • VST’s higher WACC requires higher returns, potentially creating financial burdens during the transition from coal to renewable energy.

5. Limitations and Considerations

• Data Limitations: Calculations are based on assumptions, and actual WACC requires up-to-date financials (market values, precise debt costs, etc.). WACC can vary due to fluctuating variables like interest rates, beta, and tax rates.
• Industry Characteristics: The utility sector typically has low WACC, but VST’s coal operations increase risk due to environmental regulations and market volatility.
• Market Conditions: Rising interest rates and inflation in 2022–2023 have increased WACC for both companies.

6. Conclusion

• CEG: With a lower WACC (approx. 7.02%), it benefits from cheaper capital costs and a stable nuclear-focused business. Its Microsoft contract enhances expectations for steady cash flows.
• VST: A higher WACC (approx. 7.66%) reflects greater capital costs and risks from coal and natural gas operations. Despite strong stock performance, long-term transition costs and regulatory risks may impact investments.
• Investment Perspective: Based on WACC, CEG appears to be a more stable investment, likely receiving a higher valuation in DCF analysis due to its lower discount rate.
